This lightweight material, typically found in high-performance sports cars and aerospace applications, allows for exceptional strength and rigidity while significantly reducing the car’s overall weight. This weight reduction is crucial for maximizing the efficiency and range of the electric drivetrain.

The Drive Module, on the other hand, houses the battery, electric motor, and other mechanical components. It’s constructed from aluminum, providing a stable and robust platform for the car’s powertrain. This two-part architecture allowed BMW to optimize the use of materials, placing them where they were most effective. The use of CFRP in the Life Module not only contributes to weight reduction but also enhances safety. The material is incredibly strong and resistant to impacts, providing excellent protection for occupants in the event of a collision.

Beyond the innovative use of carbon fiber, the i3 also incorporates a wide range of sustainable materials. The interior features recycled plastics, renewable raw materials, and responsibly sourced wood. The dashboard, for example, is made from kenaf fibers, a fast-growing plant that requires minimal resources to cultivate. The eucalyptus wood trim is sourced from sustainably managed forests. The i3’s commitment to sustainability extends beyond just the materials used in its construction; it also encompasses the manufacturing process itself. The i3 is produced in Leipzig, Germany, in a factory powered by renewable energy sources, further minimizing the car’s environmental footprint.

The Electric Drivetrain: Performance and Efficiency

The BMW i3 is powered by a rear-mounted electric motor that delivers instant torque and responsive acceleration. The motor’s output varies depending on the specific model and year, but it generally produces around 170 horsepower and 184 lb-ft of torque in the standard i3. The i3s, a sportier version of the i3, boasts even more power, with around 181 horsepower and 199 lb-ft of torque. This extra power translates to quicker acceleration and a more engaging driving experience.

The electric motor is paired with a single-speed transmission, providing seamless and effortless acceleration. The i3’s lightweight construction and instant torque make it surprisingly quick off the line, allowing it to accelerate from 0 to 60 mph in around 7 seconds (or even faster in the i3s). The i3’s regenerative braking system further enhances its efficiency. When the driver lifts off the accelerator, the motor acts as a generator, converting kinetic energy back into electricity and storing it in the battery. This not only helps to extend the car’s range but also reduces wear and tear on the brakes.

The i3’s battery capacity has increased over the years. The original models had a battery capacity of around 22 kWh, providing a range of around 80-100 miles.

The REx is a controversial feature, with some praising its ability to alleviate range anxiety and others criticizing its complexity and environmental impact. However, it played a crucial role in making the i3 a viable option for drivers who were hesitant to fully commit to an electric vehicle. The REx essentially acted as a bridge, allowing drivers to experience the benefits of electric driving without the fear of running out of charge.

The REx is a 647cc two-cylinder engine borrowed from BMW’s motorcycle division. It’s located in the rear of the car, near the electric motor. When the battery reaches a certain level (typically around 5-6%), the REx automatically kicks in, providing a steady stream of electricity to maintain the battery’s charge. The REx adds weight to the i3 and reduces its efficiency slightly. The range extender models also have a smaller fuel tank (around 2.4 gallons), limiting the total range extension. However, the REx provides a significant boost in range, typically adding another 70-80 miles to the i3’s total range.

Over time, as battery technology improved and charging infrastructure expanded, the need for the REx diminished. BMW eventually discontinued the REx option in some markets, focusing instead on models with larger battery capacities. However, the REx remains an important part of the i3’s history and a testament to BMW’s innovative approach to electric vehicle development.
